Answer to Question 1

The far side of our Moon and southern hemisphere of Mars are ancient and heavily cratered. The near side of the Moon has the striking mare, lava flows pulled out by our tides, while the northern hemisphere of Mars sits opposite the Hellas impact basin, and has great volcanoes on the Tharsis bulge and great plains, smoothed by either lava or water.

Answer to Question 2

Our turbulent atmosphere blurs the star's image and enlarges it.
